QUANTUM LEVITATION. "Left-handed metamaterials are known to make perfect lenses that image classical electromagnetic fields with higher resolution than the diffraction limit. For optical left-handed metamaterials, this repulsive force of the quantum vacuum may levitate ultra-thin mirrors on, literally, nothing." https://lnkd.in/eCBg2Ha View in LinkedIn

BIG NANO FORCES. "The usually attractive vacuum forces, the Casimir and the related van-der-Waals force, are significant on the length scale of nanomachines; so ideas for manipulating vacuum forces may find applications in nanotechnology." https://lnkd.in/eCBg2Ha View in LinkedIn

FLUX TUBES. "Superconductivity and magnetic field [sic] do not like each other. When possible, the superconductor will expel all the magnetic field from inside. This is the Meissner effect. In our case, since the superconductor is extremely thin, the magnetic field does penetrate. However, it does that in discrete quantities (this is quantum physics after all! ) called flux tubes." https://lnkd.in/emW6Tsg View in LinkedIn

HOW IT WORKS. "Inside each magnetic flux tube superconductivity is locally destroyed. The superconductor will try to keep the magnetic tubes pinned in weak areas (e.g. grain boundaries). Any spatial movement of the superconductor will cause the flux tubes to move. In order to prevent that the superconductor remains "trapped" in midair." https://lnkd.in/emW6Tsg View in LinkedIn

ZERO GRAVITY. "Let's think about what a superconductor really is: it's a material in which electrons are able to flow very easily. Electrons flow through superconductors with no resistance, so that when magnetic fields get close to a superconducting material, the superconductor forms small currents on its surface, cancelling out the incoming magnetic field." https://lnkd.in/emW6Tsg View in LinkedIn

ZERO GRAVITY with superconductors in a magnetic field. "The result is that the magnetic field intensity inside the the surface of the superconductor is precisely zero." https://lnkd.in/emW6Tsg View in LinkedIn

CLOAKING MAGNETISM. "If you mapped the net magnetic field lines it would show that they're bending around the object." This is the effect of a superconductor in a magnetic field leading to quantum levitation. Bending waves again. https://lnkd.in/emW6Tsg View in LinkedIn

GRAVITY. "Gravity and magnetism are not the same thing. In fact, they are completely separate forces. Gravity is a force that acts between any two objects with mass. No matter what they are made of, both objects get pulled towards each other just because they have mass." https://lnkd.in/evABxQC View in LinkedIn

GRAVITY. "The reason it seems like gravity only pulls you towards the earth is because the earth is so big that the pull from you on it isn't enough to do much to its motion." https://lnkd.in/evABxQC View in LinkedIn
